How to make the cursor start at the beginning of its contents with a QLineEdit?

[therefore]

Windows 7 SP1<br>
MSVS 2010<br>
Qt 4.8.4<br>

This code:

#include <QTGui>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QMainWindow*          window = new QMainWindow;
    QLineEdit*         line_edit = new QLineEdit;
 
    line_edit->setText("ABCDEFG");
    line_edit->setFixedSize(40,20);
    window->setCentralWidget(line_edit);
    window->show();
    return app.exec();
}

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QMainWindow*          window = new QMainWindow;
    QLineEdit*         line_edit = new QLineEdit;

    line_edit->setText("ABCDEFG");
    line_edit->setFixedSize(40,20);
    window->setCentralWidget(line_edit);
    window->show();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

Displays this:

At end.jpg

Note that the "AB" is truncated and the cursor is at the end of the line edit.

I want it to display:

at start.jpg

Here "FG" is truncated and the cursor is at the beginning of the line edit.

I've tried to setCursorPosition and cursorBackward to no avail. If I convert the text via the font metric's elidedText it will display from the beginning with the trailing "...". But I don't want to do that.

Question: Is there a way to make the cursor to start at the beginning of its contents after displaying a QLineEdit?

Actually

line_edit->setCursorPosition(0);

line_edit->setCursorPosition(0);

To copy to clipboard, switch view to plain text mode 

works just fine in the above code. I am having this problem in a much larger program where setCursorPostion did not work. I melted the issue down to a simple program for illustration but neglected to test the setCursorPostion there. I'll need to analyze further why this isn't working in my larger program.

I found my problem in my larger program: I was setting the cursor position before I was setting the text. Setting it after setting the text solved my problem.
